A consultant’s report has found that New York City’s 911 system is beset by delays and errors that endanger callers in an emergency.

Mayor Michael Bloomberg released an edited version of the report Friday.

The administration is fighting legal efforts to force it to release earlier versions of the report. It’s not clear how the 133-page document has been altered from its draft form.

The final version of the report says call operators waste time repeating questions and use inconsistent questioning procedures. It says the recently overhauled system sends some responders to the wrong address and slows fire and medical dispatchers’ efforts to give instructions to callers.
